2. A device in accordance with claim 1 having means for supporting a spider upon said plate, said spider having radially extending teeth around its periphery, and means synchronized with the rotation of said plate for moving said head upwardly and downwardly between alternate pairs of teeth.

3. A device of the character described comprising a table, a pinion journalled to rotate above said table about a vertical axis, a plate above said pinion having a downwardly extending flange around its periphery, and gear teeth upon the inside edge of said flange for engaging said pinion,

said plate having a central opening therein with its edges at every point equally spaced from the flange, an anti-friction roller journalled upon said table in position to engage said flange at a point opposite said pinion, a guide roller for engaging the edge of said opening in alignment with said anti-friction roller and pinion, a head for feeding wire to said plate, and means for moving said head radially outward from said central opening as said plate is rotated.

4. A device in accordance with claim 3 in which said plate is adapted to carry a form having an adhesive surface thereon, and said head is provided with a delivery tip for said wire adapted to cause said wire as it is fed to be embedded in said adhesive surface.

5. A device in accordance with claim 3 in which said central opening is in the form of a slot of the width of the guide roller and the periphery of said plate has parallel edges and semicircular ends, said slot extending between the centers of said ends.

6. A device in accordance with claim 3 having a bar upon said table transverse to the line connecting the center of said pinion with the axis of said guide roller, and substantially in alignment with the surface of the anti-friction roller to serve as .a guide for the flat side of the plate.

7. A device in accordance with claim 3 in which the plate is adapted to support a spider having radially extending arms and in which there is provided means for moving said head upwardly and downwardly between each alternate pair of said arms, as said plate is rotated.

8. A device for winding a, coil having straight sides and semicircular ends comprising a plate for supporting a coil form, means for moving said form parallel to the straight edges thereof without rotation, and for rotating said form about a fixed center at each end of said form, a head for moving a wire to a winding position of said form, and means for moving said head outwardly as said coil is wound at a uniform rate.

9. Means for winding a coil having parallel sides and semicircular ends comprising a plate for supporting said coil, means for driving said plate from its periphery, said plate having a periphery parallel to the turns of the coil to be Wound, said plate having a slot extending between the centers of the semicircular ends, and parallel to the sides of the said coils, and a guide fitting within said slot, a head for guiding a, wire to said form, means for moving said head regularly outwardl from said slot as the rotation progresses.

10. A device according to claim 9 having means to move said head up and down regularly as said plate is rotated.

11. A device according to claim 3 in which the plate is adapted to support a, spider having radially extending arms, and having means for sup-porting said head comprising a pivoted frame, a foot extending outwardly from said frame, and a cam driven with said pinion shaped to move said head up and down.

12. A device according to claim 3 in which the head is slidingly pivoted upon a shaft having a screw thread thereon, and in. which the head moving means comprises a half nut releasably engaging said screw thread.

13. A coil winding machine comprising in combination, a table adapted to carry a coil winding form having radially extending fingers, means to rotate said form in its own plane, an arm for feeding a wire to a point adjacent to the periphery of said form at the base of said fingers, means for moving said wire feeding means outwardly from said form as the latter is rotated, and means to move said arm vertically between said fingers as said form is rotated.
